Great job! That is an interesting strategy of pushing forward a level to build up for dropping back and nailing it. It worked and it is terrific to see someone else moving on to level 7 to inspire the rest of us.

D1. 16 rounds. Still getting the feel for this day and level. I hope to get 18 rounds on Monday.
D2. Probably about 16-17 minutes.
D3. 11:23. I really concentrated on getting pretty good range of motion on the moves, so I don't mind the time at all.

I now have an android phone so I got one of the Simplefit apps. Works pretty good, I experienced an operator malfunction on day 2.

D1. 18 rounds. I'm going to try 19 next week, then 20 after that.
D2. 13:40. The android app helped with this day. Still not rushing, but I will try to shave some time off.
D3. 10:01. Over a minute off from last week. Did this in the morning. For my lunch hour I ran 2 miles to a park where I did more pull-ups and push-ups, 20 and 40 respectively in sets of 5/10. Took a different route back for another 1.6 miles.

I tried to switch to Convict Conditioning. I did not care for it. CC did not feel like it provided the same overall conditioning aspect that SF does, what with the timed workouts. Doing SF, especially around the 6 & 7 th levels, really helped keep me thin and strong. I came back into level 3, which I beat last week. This week at level four looked like this...

Welcome back! I have not read that book, but if you want a program that is more strength oriented but still maintains and improves conditioning, I highly recommend You Are Your Own Gym. It uses both linear and undulating periodization, which means you get a bit of everything. I'm here and not there as a result of my own weakness, not theirs. It separates body parts into their own days, or push, pull, abs, and legs, and I have a bad habit of wanting to skip legs if they are separate. So I chose to do a full body program instead. Also interesting, if using that book you created your own full body program, using the methods outlined you could actually arrive at the SF plan. Although it would usually favor more difficult variations for fewer reps on strength days. But there is a method used called Stappers, and it is the exact same thing as Day 1 here. Anyway, just wanted you to know. I am sorry for sounding like an ad.

I only just started with SF again, so no room to talk; but when you mentioned CC and not getting into it much I can definitely understand.

I gave CC a try a while ago and had trouble sticking with it. I felt at one point I found a good compromise by incorporating only one or two of the skills from CC not covered in SF on off days worked really well for me, such as bridges. It didn't detract from my focus on SF nor negatively effect my performance on SF days, but I didn't feel the need to fully commit to the CC methodology.

With starting SF again, I plan to eventually work two of the CC skills back into my routine at least once a week. I hope while I may see faster progress in SF, CC's methodology will help me stay focused on long term progress and maybe provide alternatives to mix things up later with SF in the future.

Doubt that helped in any way, but good luck with your routine! Always great to read the progress you and others have made as inspiration.
